Kirkstall Lock on the Leeds and Liverpool Canal.

This is a cache in its own right but forms part of Bramley Falls Un-locked
Cache. When you find it you will need to make a note of the value of the
coin inside and where it comes from (EU or UK)
The Leeds and Liverpool Canal is the longest canal in Northern England at 127
miles long. It passes through 92 locks with a summit level of 487 feet.
The engineering of the canal is very different from other Trans-Pennine canals.
Most of the locks are concentrated in groups with long level sections between.
Tunnels and cuttings are avoided where possible with the canal following the
contours round bends and loops. In some sections the distance between points by
canal is twice the shortest distance. The earliest locks, between Leeds and
Bingley, are often grouped together to form staircases of two or three locks.
